How many nonmetals are solids, liquids and gases?
A)5,2,11
B)5,1,11
C)6,2,12
D)5,1,12

Explanation

Solution

A nonmetal is an element that is generally a poor conductor of heat and electricity. Most properties of nonmetals are the opposite of metals. There is a wider variation in properties among the nonmetals than among the metals. Nonmetals exist in all three states of matter.

Complete answer:
-A nonmetal is an element that is incapable to show any properties that are offered by the metals.
-These properties are largely determined by the interatomic bonding strengths and molecular structures of the nonmetals involved, both of which are subject to variation as the number of valence electrons in each nonmetal varies.
-Seventeen elements are generally classified as nonmetals:The elements generally classified as nonmetals include one element in group 1 (hydrogen); one in group 14 (carbon); two in group 15(nitrogen and phosphorus); three in group 16 (oxygen, sulphur and selenium); most of group 17(fluorine,chlorine,bromine and iodine); and all of group 18.
-Out of these: most are gases (hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon and radon); one is a liquid (bromine); and a few are solids (carbon, phosphorus, sulfur, selenium, and iodine).
-Hence, from the options available to us, we can see that Option B is correct.

The correct answer is B.

Note:
The state of matter depends on the intermolecular forces in between the molecules. When the force of attraction is maximum, it is solid.
